ENIn the 21st century, in the era of common globalization, we are able to observe dynamic changes in the economic development of European countries. Some of the countries – those with a rather low level of development – have improved their situation within the last couple of years, whilst others are still struggling with many problems. The worldwide crisis which started in the years 2007-2008 influenced most economies and slowed down the process of positive changes in many countries. At present time, Europe has to face yet further challenges, which are influencing different socio-economic fields of life. The aim of the article is the analysis of economic development, the presentation of changes, trends and relationships taking place in this field between the countries of the European Union. One of the most common aggregate characteristics, being the measure of economic development, is GDP per capita. The analysis of this characteristic allowed to make certain reflections. In order to achieve the intended aim we have used quantitative tools and methods. In the study we have applied selected statistic tools: descriptive statistic measures, measures of the relationship between phenomena and dynamic indicators. We have also used trend models and elementary prognostic tools. On the base of the conducted analyses we have made forecasts of the considered variable for two subsequent periods and assessed their admissibility. Moreover, using selected tools of spatial econometrics, we have examined the existence of spatial autocorrelation.
